A few weeks later, parliament was prorogued (26 June, 1716) and the king paid a visit--often repeated during his reign--to his beloved Hanover, leaving his son, the Prince of Wales, as guardian of the realm and his lieutenant. Between father and son there was never any love lost, there was a sort of hereditary family quarrel, which in this case was brought to a climax in November of the following year over the christening of a babe. The court became split up into two distinct parts. The prince was ordered to quit St. James's and those who paid court to the prince and princess were for ever banished from the king's presence.[33] [Sidenote: Trial of the Earl of Oxford, June, 1717.] After remaining a prisoner in the Tower for nearly two years, the Earl of Oxford was at length, at his own request, brought to trial. The 13th June (1717) was originally fixed as the day on which he was to appear at Westminster Hall, but this was afterwards changed to the 24th by desire of the House of Commons, who wished to put off the trial as long as possible. The lord mayor and sheriffs being directed by the House of Lords to take precautions for guarding the city's gates and preventing an unnecessary concourse of people resorting to Westminster, it was resolved to place double watch in the ward of Farringdon Without during the trial "as was done in the tryal of my Lord Winton and the like cases."[34] Fortunately for the earl, a dispute arose between the two houses on a question of procedure. The Commons were glad of the opportunity of backing out and declined to appear as his accusers, and the Lords thereupon ordered his discharge.[35] [Sidenote: Act for quieting and establishing corporations (5 Geo. i, c. 6) 1718.]
